Image and thumbnail optimization

The images are automatically resized during the process of displaying them on the page: starting from the original, a thumbnail is created that is then used in th specific context in question to optimize the loading times.
 
At present, the following image formats are supported: jpg, png, gif and webp.
 
More info: Given that the storage space of the file is normally limited, and the size involved has an impact on the maintenance costs, we recommend that you always optimize images and documents before uploading them. For example, a PDF can be brought down to low resolution, or the image can be resized to a resolution that is higher but still reasonable for the web, such as 2,000 x 2,000 pixels at 72 dpi.
